Welcome to this week's edition of 'Who Said It'!

Every week, I ask put two different popular movies, roles, or actors head-to-head to see if you can identify who said what.

This week, I am returning to the GREAT MICHAEL CERA MOVIE QUOTE SHOWDOWN. Last time, I did 'Nick & Norah's Infinite Playlist' against 'Scott Pilgrim Vs. The World', but this time, it's all about Michael Cera's high school movies - 'Juno' and 'Superbad'.
